Compared to computed radiography (CR), digital radiography (DR) is

• A. Faster, But Produces Lower Quality Images
• B. Slower, And Produces Lower Quality Images
• C. Faster, And Produces Higher Quality Images
• D. Slower, But Produces Higher Quality Images

Answer: (C)

Digital radiography is faster and yields higher quality images than computed radiography because it uses modern flat-panel detectors that convert X-rays directly to a digital signal and display the result almost immediately. This eliminates the cassette handling and laser scanning step required by CR, so image availability is nearly instantaneous and patient throughput is improved. The image quality advantage comes from the detector technology itself. DR detectors have higher detective quantum efficiency and a wider dynamic range, which means they produce clearer images with better contrast and less noise across a range of exposures. This also allows more effective post-processing to optimize brightness and contrast, and often enables good diagnostic quality at lower doses. Options claiming DR is slower or produces lower quality don’t fit these practical improvements in workflow and image fidelity.
